I construct an informationally robust auction to sell a common-value good. I examine the revenue guarantee of an auction over all information structures of bidders and all equilibria. As the number of bidders gets large, the revenue guarantee of my auction converges to the full surplus,...

A profit-maximizing Seller has a single unit of a good to sell. The bidders have a pure common value that is drawn from a distribution that is commonly known. The Seller does not know the bidders' beliefs about the value and thinks that the information structure is chosen adversarially by Nature...

We study the design of profit-maximizing mechanisms in environments with interdependent values. A single unit of a good is for sale. There is a known joint distribution of the bidders' ex post values for the good. Two programs are considered:(i) Maximize over mechanisms the minimum over...

We study the design of CDS auctions, which determine the payments by CDS sellers to CDS buyers following the defaults of bonds. Through a simple model, we find that the current design of CDS auctions leads to biased prices and inefficient allocations. This is because various restrictions imposed...

Existing models of divisible double auctions typically require three or more traders -- when there are two traders, the usual linear equilibria imply market breakdowns unless the traders' values are negatively correlated. This paper characterizes a family of nonlinear ex post equilibria in a...

This paper studies the welfare consequence of increasing trading speed in financial markets. We build and solve a dynamic trading model, in which traders receive private information of asset value over time and trade strategically with demand schedules in a sequence of double auctions. A...

We study the role of transfers in the timing of matching. In our model, some agents have the option of matching early and exiting in period 1, before others arrive in period 2; in period 2 there is a centralized institution that implements a stable matching after all agents arrive. We prove that...
